A large amount of foam appears in the slaughter wastewater. What is the cause of the foaming? Biochemical water treatment is a commonly used method of slaughter wastewater treatment, but due to water quality and process reasons, it is difficult to avoid foam problems. The foam can be defoamed by adding a waste water defoaming agent for slaughter waste water treatment. This article analyzes the causes and hazards of slaughter wastewater foaming, and aims to provide defoaming solutions with good defoaming effects and low input costs.
The cause of slaughter wastewater foaming
Slaughter wastewater contains oily lipids, hair, feces and other dirt, which is generally reddish brown. High-concentration organic matter is not easy to degrade and it is difficult to handle. However, a lot of bubbles are prone to appear in the process, mainly due to the following reasons.
1. The water contains fatty acids and surfactants, and there will be a lot of scum bubbles during aeration;
2. The sludge retention time of the system is longer and the sludge return rate is lower. A lower F/M ratio will cause the excessive growth of filamentous bacteria and cause foam;
3. Unreasonable process selection and collocation, resulting in excessive load of the biochemical pool, insufficient oxygen, and insufficient microbial activity;
4. Slaughter wastewater contains a lot of oil and blood, and the ratio of carbon to nitrogen and carbon to phosphorus is large. The nitrogen and phosphorus are relatively insufficient, and oily foam is easily produced.

The hazards of slaughter wastewater foaming
1. Pollution of the environment: Excessive foam in the biochemical pool affects the appearance and overflows and pollutes the environment;
2. Foam causes sludge loss: Foam loosens the sludge and increases the index, which is prone to high viscosity expansion and cause sludge loss.
3. Deterioration of water quality: Too many bubbles and too thick will affect the reproduction of microorganisms, causing the water body to become hypoxic, reducing the oxygenation efficiency and deteriorating water quality.
Defoaming solution for slaughter wastewater
Slaughter wastewater is difficult to avoid foaming due to the composition of the wastewater and the treatment process. The foam in the slaughter wastewater needs to be treated in time, otherwise the overflow of the foam will easily pollute the environment, affect the treatment process, and cause the water quality to deteriorate. So how should the foam of slaughter wastewater be eliminated? Adding defoamers is a good solution, but there are many types of defoamers, and only the right formula can achieve a multiplier effect.
Nanhui defoamer manufacturer is prone to a large amount of foam in the slaughter wastewater treatment. The waste water defoamer developed and designed according to the purpose is a compound defoamer. The dosage is small, but the defoaming is highly targeted and defoaming. It has good effect and is very convenient to use. It is a kind of water treatment defoamer with good performance and high cost performance.
